To all who/m, t may concern.'

Be it known that I, KATHERINE SZLEMKO,

a citizen of the United States, residing at Chester. in the county of Delaware and State of Pennsylvania, have invented new and useful improvements in Egg-Boaters, of which the following is a specification.

This invention relates to egg beaters, and one of its objects is to provide a device of this character which is simple, strong and durable, susceptible of manufacture and sale at a comparatively low cost, and adapted to be easily and conveniently operated.

A further object of the invention is to provide a beater having a beater head of novel construction, whereby rapidity of action and efficiency are obtained.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawing in which Figure 1 is a side elevation of an egg beater embodying my invention. Fig. 2 is a sectional plan view on the line 2-2 of Fig. 1, through the beater shank and looking down upon the beater head. Fig. 3 is a vertical section through the beater head on the line 3 3 of Fig. 2. Fig. 4 is a bottom plan view ofthe beater head.

In carrying my invention into practice, I provide a supporting bracket 1, having upper and lower bearing members or sleeves 2 and 3, arranged in vertical alinement, a bearing socket 4 arranged opposite and in parallel relation to the sleeve 2 and connected therewith by a cross piece 5, and a longitudinally curved arm 6 extending between and connecting the sleeve 3 and socket 4, whereby the parts of the bracket are joined to form a unitary structure. This bracket may consist-of a single casting, and an arm 6 is suitably formed and arranged in practice to provide a handle by which the device may be held in one hand while the other hand is employed to operate the beater head.

Extending through and journaled in the sleeves 2 and 3 is a spindleV or shank 7 carrying at its lower end a beater head 8 and at its upper end a pinion 9 retained in position by a screw or other suitable fastening 10, the pinion 9 serving in conjunction with an annular flange or collar 11 as stops bearing respectively against the sleeves 2 and 3 to hold the shank or. spindle against onda wise movement, while permitting it to revolve freely in said sleeves. A spindle 12 is suitablymounted upon the bearing member 4 and has Ajournaled thereon a drive gear 13 provided with an actuating crank 14, which gear meshes with the pinion 9 whereby the shank and beater head are adapted to be revolved for the beating action.

The beater' head 8 may be integral with the lo-wer end of the shank and is provided with an annular series of beating arms or flukes 15 which are grouped about the shank, the head terminating at its base in a conical portion 16 provided with radial grooves 17 leading from the apex thereof y to the clearance spaces between the beater arms so that the head may revolve in contact with or close in proximity to the bottom of a receptacle containing the eggs, while maintaining a beating action upon the portion of the eggs below the beater arms. The said beater arms are comparatively thick and flat at the base and are thence rounded and tapered toward their free ends or points. They are also curved on the arc of a circle extending from the shank upwardly and outwardly and thence inwardly toward the shank, and they are furthermore curved spirally in a direction around and concentric with the shank, so that each beater arm as it revolves will tend to throw the material upwardly and inwardly into the path of the overhanging spiral portions, and then to strike and throw the material downwardly, the beaters thus operating to momentarily retard the material against being thrown out by a centrifugal force and to give a secondary beating action on each revolution on the same portio-n of the material, whereby vthe beating effect is greatly increased and the beating eiiiciency enhanced. By thus acting on the material it would agitate it vertically as well as horizontally in each beating operation and prevent it from working away from the beaters too quickly under centrifugal force, by means of which a given amount o-f material may be beaten to the highest possible degree within a minimum period.

It will thus be understood that the device, in addition to presenting a novel construction of handle and bearing bracket, provides a novel construction andarrangement of beating blades in a beater head, whereby a beater of superior character is produced.

I claim f 1. An egg beater including a rotary beater head formed of a substantially conical body having an annular series of integral spaced beater arms, and a shank integral with the body and extending up wardly therefrom and surrounded by said beater arms, the beater arms being provided with spirally curved tips extending on arcs concentric with the shank, said body being provided with aconical base portion formed with radial grooves cut therein and communicating with the spaces between the beater arms.

2. An egg beater comprising a bearing bracket, a shank journaled t0 revolve upon the bearing bracket, means for revolving said shank, and a beater head upon the shank comprising an annular series of arms or iiukes grouped about the shank, said arms being of maximum thickness at their base and minimum thickness at their extremities, each arm being curved on an are outwardly and upwardly from the base thence inwardly toward the shank, and having its upper portion tapered toward its free end and curved spirally in a direction concentric with the shank.

In testimony whereof I aiiX my signature in presence of two witnesses.
